Lamm LL2.1 Deluxe "DC Offset"?


Hi there,

Is there anybody who has a deep experiences with high fluctuated "DC offset" in Lamm LL2.1 Deluxe PreAmp?.

My Lamm LL2.1 Deluxe Preamp shows a highly fluctuated DC reading that reaching +-200mV even more. Last night measurement showed a flucuated reading and reached +-300mV.

A three weeks continuous observation shows that the preamp DC fluctuation seems higly affected by the swing/fluctuation of AC Volatage,day time and night time. I can see that even as small as 0.3V AC voltage abrupt swing will directly generate significant DC offset in the LL2.1.

Your sharing experience and advices are higly appreciated.

Am very very surprised by LAMM's lack of effective response to resolve the issue. And this, coming from such a reputable company, can only augur bad things for the company.

I was seriously considering buying a Lamm pre but after reading this, no way... not with such mentality....
I think in such cases, action from those who pocketed the money for the new gear should speak louder than words. Why can't LAMM arrange delivery through his dealer of another pre to Gr-gin, and take back the "unsatisfactory" unit from the customer for some serious indepth testing, repair and outright replacement if need be?

I just cannot understand the behaviour and attitudes of manufacturers in such cases. What they have to lose through negative publicity needs to be carefully weighed in the decision of leaving the customer sob his heart out or regret his purchase ....

Remember there have been reputable audio manufacturers driven out of business through their own inability or unwillingness to support customers in difficult times as these...

Why should the onus always be on the customer? Why can't the manufacturer or his appointed dealer make a commercial gesture and at the same time create a goodwill... What will this cost to the manufacturer?

After this ongoing saga of unresolved issue one thing is certain, no LAMM product will ever enter my audio room..... that's it.
